8 Claims.

This invention relates generally to radio receiving apparatus and refers more particularly Vto a lamp constructed to embody the several instrumentaliti'es of the receiving apparatus. 5" One of the principal objects of this invention consists in arranging the several instrumentalities of the radio receiver in compact groups and distributing these groups in diierent portions of the lamp in such a manner that the eciency of 10? either the lamp or the radio receiver is not impaired.

Another advantageous feature of the present invention consists in predeterminedly arranging V the instrumentalities of the radio receiving appa- 1li ratus in the different portions of the lamp in such a manner that the design of the lamp is not unduly restricted and so that all of the parts of the radio receiver, with the exception of the controls, are concealed from vievv.

A further object of this invention consists in the provision of a combined lamp and radio receiver so constructed that the various parts of the receiver are rendered readily accessible for repair or other purposes.

In addition to the foregoing, the present invention contemplates a combined lamp and radio receiver capable of being inexpensively manufactured and readily assembled. This feature, as well as the above objects, will be made more apparent 80y as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

Figure I is a cross sectional view taken substantially on the plane indicated by the line ID-Ill of Figure 8.

Referring first to the embodiment of the invention illustrated in Figures 1 to '7, inclusive, it will be noted that there is illustrated in Figure 1 a lamp I having a base portion I6 and a shade assembly Il supported in spaced relation from the base by means of a pedestal assembly I8. In the present instance, the instrumentalities of the radio receiving apparatus are divided into three groups and the'latter are respectively supported in the base I6, pedestal I8, and shade assembly Il.

Although the particular parts of the radio receiver contained in any one group may be widely varied without departing from the spirit and scope of this invention, nevertheless, I prefer to arrange the variable condensers I9 in the base I6 of the lamp and the speaker unit in the shade assembly I1 of the lamp.

In detail, the base I6 of the lamp is provided with a bottom plate 2| and a cover 22 detachably secured to the bottom plate by means of the fastener elements 23. The cover 22 forms a housing for the plate 2 I, and several of the instrumentalities of the radio receiving apparatus, including the condensers I9, are supported on the plate 2l within the housing. The variable condensers I9 are symmetrically arranged on the base with respect to a centrally disposed upwardly extending tubular member 24 secured to the plate 2l and having a reduced portion 25 extending through a central opening 26 in the top wall of the cover. 35 The reduced portion 25 terminates at the upper end in an enlarged tubular portion 2l and the latter forms a support for the pedestal I8.

'Ihe pedestal I8 of the lamp is shown in Figure 2 as having a vertically extending tube 28 seated at the lower end on a plate 29 and adapted tovbe concealed by an ornamental tube 30. The ornamental tube surrounds the tube 28 and is also seated on the plate 29 at the lower end thereof. A chassis unit 3l supporting a plurality of instrumentalities of the radio receiving set is telescoped by the tube 28 and is shown in Figure 5 as having a vertically extending stanchion 32 Welded, or otherwise suitably secured, at the lower end thereof to the plate 29. The stanchion 32 is arcuate vin cross section and cooperates with the tube 28 to provide laterally spaced vertically extending compartments 33 and 34. Upon reference to Figures 3 and 4, it will be noted that the opposite vertical edges of the stanchion frictionally engage the inner surfaces of the tube 28`and thereby serve to secure the latter with the ornamental tube 30 against lateral displacement relative to the plate 29.

Ihe plate 29 is supported upon circumferentially spaced lugs extending inwardly from the upper end of the tubular member 24 and is detachably secured to these lugs by means of the fastener elements 36. With this arrangement, it

r,will be noted that the chassis unit 3| may be disassembled from the base I6 when desired by merely removing the tubes 28 and 3U and the fastener elements 36. It will, of course, be understood that prior to disassembling 'the chassis unit 3| from the base I6, it is necessary to also disconnect the electrical conductors extending from the parts of the radio receiving circuit in the base to the various instrumentalities of the apparatus supported on the chassis.

In accordance with the present invention, parts of the radio receiving circuit `are supported in the compartment 33 on the stanchion 32 and additional instrumentalities of the radio receiving circuit are carriedby the stanchion 32 v.at the opposite side thereof in the compartment 34. In the specific embodiment of the invention illustrated in Figures l to 1, inclusive, two of the radio tubes 31 and 38 are supported on the stanchion 32 in the compartment 34. The base of the upper tube 31 is secured to a plate 39 which, in turn, is welded, or otherwise suitably supported upon a plate 40 extending transversely fixed, to the upper end of the stanchion 32 and is formed with the required number of sockets therein for receiving the usual prongs extending from the base of the tube. The lower tube 38 is of the compartment 34 and xedly secured to the stanchion 32 in Vertical spaced relation to the plate 29. The plate 40 is also formed with the f. required number of sockets therein for detachably receiving the prongs extending from the base of the tube 38. The aforesaid sockets are electrically connected in the radio receiving lcircuit in accordance with conventional practice and cooperate with prongs on the radio tubes to connect the various parts of the circuit to the elements in the tubes. The space between the two tubes is occupied by the parts 4| of the radio receiving circuit and the tube 31 is shielded fromthese parts by means of a plate 421 also extending transversely of the compartment 34 and xedly secured to the stanchion 32. The arrangement is such that the two tubesare effectively shielded from the instrumentalities of the radio receiving y apparatus 4| and are also shielded from the parts n of the circuit in the compartment 33.

Attention is called to the fact at this time that the stanchion 32 is apertured as' required to provide for extending any electrical conductors therethrough and that the tube 28 is slotted, as at 43, oppositethe radio tubes in order to permit the latter to be interchanged without removing the tube 28.

From the foregoing construction and from the illustration noted in Figure 5 of the drawings, it will be seen that removal of the ornamental tube 30 and the inner tube 28 exposes all of the parts of the radio receiving circuit supported on the chassis unit 3|. This is desirable in that it renders all of these parts .of the radio receiving circuit accessible for testing and repair without the necessity of disassembling the chassis.

Referring again to Figure 5it'will b e noted that the chassis unit 3| also includes a contact plate 45 secured in vertical spaced `relationship to the plate 39 by means of the fastener elements 46 and the spacers 41 surrounding the fastener elements. The contact plate 45 is formed with a plurality of sockets 48 therein electrically connected to those parts of the radio receiving 5 circuit it is essential to connect to the speaker unit 29 in the shade assembly I1. The sockets 48 are respectively engaged with suitable prongs 49 extending downwardly from a plate 50 and electrically connected to the speaker unit by 10 means of the conductors 5|.

. The plate 59 is detachably secured to a flange 52 in spaced relation thereto by means of the fastener elements 53 and the spacers 54. The flange 53 is xedly secured to the lower end of 15 a tube 55.having the upper end secured to a housing 56 in the shade assembly I1. Upon reference to Figure 2, it will be noted that the flange 53 is in the form of a plate abutting the upper edge of the tube 28 and clamped to the latter 20 by means of a ring 51. The ring 51 is rotatably mounted on the lower end of the tube 55 abovethe plate 53 and is internally threaded for en-l gagement with the external threads formed onV the upper end of the tube 28. It will also be ob- 25 served from the above figure that the bottom surface of the ring is recessed, as at 59, to receive the top edge portion of the ornamental tube 30 and thereby hold the same in assembled relation with the tube 28. 30

With the above construction, it will be noted that both the ornamental tube 38 and the chassis enclosing tube 28 may be readily removed from the chassis by merely disengaging the ring 51 from the upper threaded end portion of the tube 35 28 and by moving the contact plate 50 upwardly relative to the cooperating contact plate 45 to disengage the plugs 49 on the former from the sockets 48 in the latter. After the chassis unit 3| has been exposed, the same may be readily 40, removed from the base |6,if desired, by disengag-V ing the fastener elements 36 and any electrical conductors extending from the chassis unit to the parts of the radio circuit in the base I6. In this connection, it is to be noted that the several parts of the radio circuit in the base |6 may also be rendered accessible without disassembling the lamp structure. As shown in Figure 1, the raised4 portion 60 on the top wall of the cover 22 is re-v movable from the latter and the central opening 6| in the top wall of the cover is of suicient diameter to permit the'cover to be raised over the ornamental tube 30 after the fastener elements 23 have been manipulated to disconnect the base plate 2| from the cover. It follows from the above that all of the various parts of the radio receiving circuit in the pedestal and in the base may be readily rendered accessible for observation and repair.

Referring now to the construction of the lamp shade assembly n, it will be noted that the hous- 0 ing 56 is positioned within the shade 63 and forms a support for the electric light bulbs 64. Located within the housing 56 is the usual power transformer 61 for the rectifier and audio tubes 68 and 65 69 of the speaker unit 20. The speaker unit 20 is supported on the upper' end of the housing 56 within the shade 63 and the cone 10 of the speaker is supported in the manner shown in Figure 1 adjacent the sounding board 12 which forms the 70 top of the shade assembly.

Upon reference to Figure 1, it will be noted that the base I6 of the lamp supports the combined volume control and on-and-off switch 14. This switch is shown as being secured in the tubular 76' usV member 24 and is actuated byy means of a shaft 15 having the lower endremovably connected to the switch 14. The shaft 15 is rotated to effect the desired operation of the switch 14 by means of a revoluble control disc 16 supported on the upperend of the tubular member 24 beneath the plate 29 and having internal teeth 11fmeshing with a pinion 18 which, in turn, meshes with a gear 19 secured to the upper end of the shaft 15.

In Figures 6 and 7, I have illustrated one type of mechanism that may be employed for varying the capacities of the several condensers I9. accordance with conventional practice, each of the variable condensers I9 is provided vwith a rotor having a vertical shaft 8| secured at the upper end to a pinion 82. The pinions 82 on the condenser shafts are adapted to mesh with a centrally disposed driving gear 83 rotatably supported on the tubular member 24 and adapted to be driven by a revoluble control disc 85 through suitable reduction gearing. The control disc 85 is rotatably supported beneath the control disc 16 and is provided with internal teeth 81 adapted to mesh With an idler pinion 88 which, in turn, meshes with a ring gear 89 fixed to the-reduced portion 25 of the tubular member 24. As shown in Figure 1, the idler pinion 38 is rotatably supported on the free end of a link 90 having the opposite end pivotally connected to a carrier disc The carrier disc 9| is centrally apertured to receive the reduced portion 25 of the tubular member 24 and is supported on the upper edge of a sleeve 92 having spaced projections 92 depending from the lower edge for engagement in radif ally extending slots 9|" formed in the hub 93 of the driving gear 83. The upper edge of the sleeve 92 is also formed with spaced projections 93' for engagement in radially extending slots 94' formed in the carrier 9| and the latter slots, as well as the slots 9|', are elongated radially of the axis of rotation of the sleeve to permit shifting movement of the sleeve in a direction transversely to its axis. In the present instance, the sleeve 92 is normally urged in a direction to frictionally clamp the pinion 81 between the xed gear 89 and the control disc 85 by means of a spring 95 acting upon one of the projections 93 and adjustably connected to the carrier 9| by means of the set screw 95. As shown, the set screw 95 is threaded in a lug projecting upwardly from the carrier and extends freely through the projection 93 aforesaid on the sleeve 92 for connection with the spring 95. Inasmuch as the control disc 85 is mounted on the sleeve 92 for movement therewith as a unit, it follows that the spring 95 urges the control disc 85 in a direction to tension the pinion 81 between the gear 89 and control disc. As a result, backlash is eliminated from the gearing and more accurate control of the condensers is obtained. Attention may also be called to the fact that a wave band indicator 96 is secured to the control disc 85 for rotation therewith as a unit and that this disc is visible through a window 91 formed in the raised portion 80 of the cover 22.

The embodiment oi the invention illustrated in Figures 8 to 10, inclusive, differs from the one previously described in the construction of the chassis unit |00. This chassis unit is designed for use with radio receiving apparatus of a larger capacity than the one shown in Figures 1 to 7, inclusive. 'I'he stanchion |0| in this embodiment of the invention comprises two semi-circular vertically extending sections |02 arranged back to back and integrally connected together, as at |03. These sections cooperate with the enclosing tube |04 of the pedestal to form, in effect, four verti.` cally extending compartments respectively designated in Figure 10 by the reference characters |05, |06, |01, and |08. The compartments. E|06 and |08 are each identical to the compartment 34 previously described and in the interests of simplicity, each compartment is shown as housing the same instrumentalities of the radio receiving circuit. The compartments |05 and |01 preferably contain the wiring and other parts of the radio receiving circuit necessaryfor `elcient operation of the radio. With the above excep tions, the embodiment shown in Figures 8 to 10, inclusive, may be identical to the one described indetail with reference to Figures 1` to 7, inclusive, and, accordingly, reference is madeto the foregoing description for an explanationof-the tuning dial arrangement and the other identical parts. f n Y f What I claim as my invention is: Y
